- match_re:
alertname: WEBLOGIC-wls_threadpool_hogging_thread_count
instance: (ljade)*
That regular expession matches only:
""
"ljade"
"ljadeljade"
"ljadeljadeljade" ... etc
- match_re:
alertname: LINUX-node_filesystem_nfs_used_percent
instance: ljade*
That regular expression matches only:
"ljad"
"ljade"
"ljadee"
"ljadeee" ... etc
To match any string beginning ljade, you need:
instance: 'ljade.*'
(The quotes may not always be necessary but are a good idea, since YAML can
do some odd things with special symbols in certain situations, particularly
colons and asterisks)
